Sleep Regression?

Ladies I need help. I’m miserable. My son has been such a great sleeper for the past couple of months. Sleeping 10-12 hours a night in his room. He gave me a little taste of a normal sleep schedule. Now all of a sudden he was waking up once during the night for 3 nights in a row. Okay, not a big deal, gave him a bottle and he went right down. Then it was twice a night for a couple more nights in a row and it was harder to get him down and stay asleep once transferred back to crib. Now it’s like every 2-3 hours for the past two nights. And every single time I try to transfer him to the crib he wakes up immediately and starts crying. His naps has also decreased tremendously. I thought he was just going to two long naps rather than a 3-4 short naps. No. It’s still like 2 naps, but now they are 20-30 min. I can’t win. I’m so exhausted. I need advice. My husband works during the day and I’m a SAHM so the nightshift has and will always be just on me. I don’t get any help. And I’m so tired and miserable. -Signed a tired mama who just spent 2 hours trying to get her son to stay asleep in his crib.
